MONDAY, 3:44pm: The move is official, the team announced.
SUNDAY, 5:53pm: Boston has indeed waived Eddie, as is shown on the RealGM transactions page.
SATURDAY, 6:26pm: The Celtics are waiving Jarell Eddie, tweets Eric Pincus of Basketball Insiders. Pincus indicates that the move has already taken place, though the team has yet to make an official announcement. The undrafted rookie was claimed off of waivers by Boston Thursday after the Hawks released him from their training camp roster.
His one-year contract was non-guaranteed, so Boston merely inherited his D-League rights and no actual costs by claiming and waiving the small forward. Of course, another team could still claim Eddie off waivers from the Celtics, which would remove those D-League rights from Boston. Eddie spent time with the Wizards summer league team, and he impressed Atlanta brass in his preseason tenure there.
